Patented Mai. 25, 1913.

To all whom it may concern Be it known that we, ADAM ROSENKBANZ, acitizen of the United States, resident'of West View, in the countyofAllegheny and State of Pennsylvania, and JOHN LOUIS LANGNER, a citizenof the United States, resident of Cleveland, county of Cuyahoga, Stateof Ohio, have invented a new and useful Improvement in WrappingMachines; and we do hereby declare the following to be a full, clear, andexact description thereof.

Our invention appertains to a machine for wrapping commodities andsealing the folds of the wrapper around the article, and particularly tothe wrapping, of loaves of bread.

The object of our invention is to provide a machine which willmechanically and automatically arrange the wrapping material, convey thearticle into position relative to the wrapping material, wrap and sealthe article in the wrapper, and finally discharge the article in thesealed wrapper from the machine.

In the accompanying drawings Figure 1 is a side elevation of ourinvention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a sectional planon lines 111111 of Fig. 1. Fig. 4 is a rear elevation of Fig. 1. Figs.5,

6, 7, 8, 9, and 10 are enlarged detail views of parts of our invention.Figs. 11, 12, 13, 14: and 15 are enlarged detail views showing operativepositions of the parts looking in the direction of Fig. 1. Figs. 16, 17and 18 are similar views of other parts of our invention, looking in thedirection of Fig. 4. Figs. 19, 20, 21,22 and 23 areviews showing theprogressive stages of the wrapping operation.

, Reference numerals in the following specification refer to like partsin the drawings, in which a main support 2, havin a superstructure 2, isprovided with suita le bearings in which are carried a series of shafts.The shaft 3 carries a pulley 4 and pinion 5, the latter meshing with thegear 6 on the shaft 7 which is provided with mitered gears 8, 8 engagingsimilar gears 9, 9 on the shafts 10 and 11, thelatter shaft beingoperativelgeconnected to the shaft 12 by means of the veled gears 13.'The pins 14 '(Fig. 3) are each provided with a series of arms. The arms15 extend through slots in the plate 16 of the main support'2, (Figs.1-2) and are provided with suitable yokes and operated by the links 16and cams 16". These arms carry at their'upper ends the top folders 17which in open relation have an intervening space 18 between them.

Horizontally arranged on each side of the top folders are side folders17 carried on the arms 17 and operated by the links 18 and the cams 18*,(Figs. 1-3) and secured to the lugs 20 and having a vertical movementare the links 20 having thereon the heads 21, 21 to each of which headsthe end folders 22, 22 (Figs. 416) are flexibly connected, the links 20being operativel engaged to the forked arms 23, 23 whic are operated bythe cams 24, 24:. Adjacent to the end folders 22 and for the purpose ofheating said end folders are heating ets 25, and carried by the heads 21are paste depositors 26.

Positioned on opposite sides of the space 18 and below said top foldersare the small buffers 19 which are suitably connected to the levers 19'fulcrumed at 19 and operated by the cams 19 and springs 19. Brackets'acarry a spindle b on which is a roll of paper 0', the free end of whichis ex-' tended between the rollers d, d which are suitably arranged onthe upright e secured framing e, (Figs. 1, 2,7). The. shaft 30 has amutilated gear 31 adjacent to the sprocket wheel 29 and meshing with areduced gear 32 on the shaft 33, on the opposite end of which is anintermediate gear 34 meshing with a gear 35 on the shaft 36 of theroller d (Figs. 17). A sector 37 is secured upon the shaft 30 andengages a gear 38 on the shaft 39 which is provided with a suitablemember 40 having radially projecting ends in which are suitably securedtongues preferably of flexible material and which are adaptedtocirculate within a glue or mucilage container 41 by the operation bfthe shaft 39.

On each side of the plate 16 slotted stand ards 42 are secured, and acutter 13 (Figs. 14) adapted to be moved to and from a cutter bar 44 issupported upon the compression springs 45 which are held in position bythe straps 46, the ends of which are connected at 46' to the sides ofthe cutter protruding through the slots in the standards, and a push-bar47 is. pivotally connected at 47 to the strap 4-6 and supported freelyon the pin 18 on the end of the hanger 49 (Figs. 13) which is suitablysuspended from theplate 16, the'other end of said push-bar beingprovided with a roller 50 which rides against the periphery of the cam51 (Fig. 3). for 'the purpose of operating the cutter by the action ofsaid cam.

A movable frame 52 (Figs. 1, 8, 9,10) formed of a series of upper andlower parts being separated by'the transverse strips 54:

to forma clearance or passage 55 in which the strips 53 serve as guidesfor paper delivered into said passage, is slidably mounted on ways 56suitably secured on the sides of the superstructure '2, so that saidframe may be moved to and fromthe rolls d, cl. Arms 57. are carried uponthe'pins 14 (Figs. 1, 3) the upper ends of said arms being provided withsuitable slots which-engage the studs 58 which are suitably connected tothe frame 52, the said-arms being opera-' -tive1y controlled in onedirection by the cam 61, connecting rod 59, and link 60 and ,the, returnmovement being effected by the spring 61 (Figs. 1, 3). A small griplever 62 having forked end 62' and fulcrumed at 63 on the standard 64which is suitably secured to the plate 16, is connected by the link 65to the cam 66 by which said lever is maintained. with its downwardlyinclined ends 65 raised above the top of the small stand 67(Figs. 1, 11)against the tension of coil spring 68 which is suitably secured to theplate 16 and to said levers 62 to draw the ends 65 down upon the top ofthe stand 67 when the action of the cam 66 is withdrawn from the lever.A chute 69 (Figs. 1, 2) formed of the sides 69 is elevated and supportedat one end thereof by the support 70, the other end of the chutedeclinesto and is suitably supported in connection with the shaft 71which is provided with a crank 72 to which is secured one end of thelink 71.

- the other end of said link being attached to the crank 72 on the shaft7 to operate the star wheels 72 which are carried on the shaft 71 withinthe chute, the bed portion 73 of the chute extending between the-starwheels vand being carried over the shaft 71, its lower end falling inperpendicular alinement with one side of the space 18 and opposite tothe lower extremity of the part 73 a guard 74 is arranged, its'lower endterminating parallel with the lower end of the part 73 and on each sideof the part 73 and guard 74 are side-guards 75 which are suitablysecured to the parts 69, the lower ends of the guards coiiperating toform a rectangular end to the chute through which the articles aresupplied to the space inclosed by the wrapping mechanism, the lowerconfines of -which form part of theplate 16 and consist of twodownwardly swinging doors 76 suitably hung at 76 to the underside of theplate 16, and links 77 operatively secured to the underside ofsaidkdoors and to the cams 78 (Fig. 3) by which the doors are operatedto permit the passage of articles from the space 18 after the .operationof wrapping has been completed and from where the package descends bygravity onto an endless carrier 79 carried on the drums 80 suitablymounted on the brackets 81 on the main support, and'operated by thepulleys 82, 83, andbelt 84.

With the parts of our inventionconstructed and assembled as shown anddescribed .andwith the mechanism in the' positions shown in Fig. 1, thewra ping material on a the feeder roll having its ree end startedbetween the rolls, and the articles to be wrapped furnished to thechute, the opera tion of our machine is as follows: Motion is impartedto the pulley 4 by anysuitable means, thus operating the shaft 3 andpinion 5, the latter operating the gear 6 andshaft 7, thereby actuatingthe mitered gears 88 and 9, 9 and transmitting a continuous movement tothe shafts 10, 11, 12 andto the several cams carried b said shaft. Thesprocket Wheel 27, on the shaft 12, the chain 28 and correspondingsprocket wheel 29 be ing thereby driven and operating the mutilated gear31 and reduced gear 32 by which the shaft 33 and gear 34 are operated toactuate the feed roller d by engagement with the gear 35, the rollerwill then feed the paperinto the adjacent end of the movable slideduring one revolution of the roller when the free end of the paper willbe beyond the opposite end of the frame 52, then the mutilated gear 31will pass out of engagement with the gear 32 at a moment when the cam 61is timed to act against the roller 61 and force the push-bar to operatethen makes a deposlt upon the paper in the frame 52 through a transverseo ening at 52 in the frame which exposes the under- Ill side of thepaper to the action ofthe paster until one of the radial ends has beenbrushed against the same to deposit paste thereon, immediately followingwhich the cam 51 acts against the roller 50 to draw the cutter 43 downand sever the paper against the cutter-bar 44, and upon the completionof the downward movement of the cutter the continued movement of the cam51 immediately withdrawing its action from the roller 50 and permittingthe springs 45 to return the cutter to its higher position within thestandards. The cam 61 is then turning from against the roller 61 byreason of which movement the spring 61 is free to reverse the arms 57and return the sliding frame back to the feed rollers, the severed sheetof paper being retained in position over the space between the foldersby the grip lever 62 to receive a loaf from the chute 69 which isdirectly above said space and into which the loaves are .fed singly bythe movement of the star wheel 72 which movementis effected by the link71 on the crank 72 actuated by the shaft 7, and forcing the pawl 71,carried on the crank 72*, against the ratchet wheel 71 the latteractuating the shaft 71 to thereby turn the star wheel until the carryingmember thereof will have turned so as to perimt the loaf to gravitatefrom the wheel and the hopper, and by reason of the radial stroke of thecrank 72 being greater than that of the crank 72 the movement of theformer is oscillatory and the pawl 71 is carried back to reengage theratchet-wheel 71 preparatory to each subsequent operation thereof. Theloaf B descends through the hopper, alights upon the wrapper A whichhaving one end free settles down between the folders with the loaf andassumes the folds C shown in Figs. 13, 19. The cam 66 is turned to thenoperate the gri lever 62 to release the end of thepaper hel thereby,during which operation the cam 19 is releasing the lever 19'sufiiciently to permit the springs 19 to move the buffers 19 to compressthe wrapper snugly against each side of the loaf (Fig. 13) while thecams 16 simultaneously close the arms 15 to operate the top folders 17Fig. 14 which are thereby carried against the wrapper to form the foldsD and seal the same across the upper side of the loaf (Fig. 20)following which the cams '18 operate the arms 17 h to pass the sidefolders 17 against the projecting sides of the wrapper and compress andpartly fold the same against each end of the loaf (Fig. 15)' with theeffect of formlng the folds E shown in Figs. 16, 21, and then instantlywithdraw said side folders, whereupon the upper links 20 to which areattached the small paste depositors 26 are operated by the movement ofthe cams 24, to bring the end folders 22 down upon the protruding endsof the wrapper to thoroughly form and compress the folds G and todeposit paste on the lower projecting end of the wrapper, as shown inFig. 17, so that the wrapper is then as shown in Fig. 22. When thereturn movement of the upper links is commenced, the cams 24: operatethe lower links 20 to swing the lower end folder 22 against theprojecting and pasted ends of the wrapper to form the folds H and closeand seal the same upon the package, (Figs. 18, 23) completing thefolding operation. The cams 19 are timed to then operate the lever 19 towithdraw the buffers 19 from the package in the recess, whereupon thecams 78 carry back the links 77 to open the doors 76 leaving the packageto descend by gravity from the recess to the carrier 7 9 by which it maybe conveyed to any desirable point and discharged. r

If a paraflined wrapper is used, the use of a paste depositor may not benecessary, and the heating of the end folder, as shown, may be reliedupon'to heat the paper sutficiently during its contact therewith tocause the end folds to adhere together.

Modifications and changes may be made both in the construction andoperation of the various parts of the machine herein shown anddescribed, without departing from the spirit of the invention.
